Intermittent impacting type press roller

Abstract

The invention provides an intermittent impacting type press roller, and belongs to agricultural machinery. A swinging rod is hinged and connected onto the bottom of a height regulating frame; a roller frame is hinged onto the lower side part of the swinging rod; a roller shaft is assembled on the roller frame; a non-cylindrical impact press roller is arranged on the roller shaft through a bearing; N lug boss type lifting sections are uniformly distributed and arranged at intervals on the outer surface of the non-cylindrical impact press roller in the direction along the axis line; a plurality of projected transverse edges are arranged on the outer surface of the lug boss type lifting section in the direction along the axis line of the non-cylindrical impact press roller; the two ends of a buffer shock absorber are respectively hinged onto the lower side part and the upper side part of the height regulating frame assembly. The roller has the advantages that the structure is novel, simple and reasonable; the compression intensity on the soil is great; the compression operation quality is high; the use is reliable; the applicability is high.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a pressure roller for compacting soil. Background technique [0002] The pressure roller is a common soil-contacting part in agricultural machinery, and it is mainly used for compacting the soil after plowing and sowing operations. Among them, repression after sowing is an important technical link in dryland operations. Its function is to increase soil compaction, reduce water evaporation in the soil, reduce pores in the soil, and make the seeds closely contact with the surrounding soil, which is beneficial to the seed's growth. germination and emergence; in addition, spring sowing suppression can also play a role in increasing ground temperature. Existing pressure rollers are traditionally mostly cylindrical, and when the cylinder is placed horizontally, it becomes a pressure roller, and its material is mostly cast iron or low-carbon steel. During operation, the pressure roller i...

AI Technical Summary

Problems solved by technology

During operation, the pressure roller is driven by traction machinery, and the soil can only be compacted by the gravity of the pressure roller itself during rolling. There is a problem of insufficient pressure, and it is easy to stick the soil on the surface of the seed, increasing the disturbance of the soil and damage, so that the soil moisture loss is serious, increasing the working resistance, if necessary, it needs to be shut down for cleaning, which reduces the working efficiency and affects the germination and emergence of seeds
